San Francisco 49ers FB Bruce Miller (shoulder) is likely to miss the rest of the regular season and playoffs after injuring his left shoulder in Week 15. "It doesn't look good. It looks like he has an injury to his scapula," head coach Jim Harbaugh said. "He does so many things in the protection, in the run game, receiving out of the back field. He is a multitalented, multi-use player. Special teams contributor on two, three phases. It's a loss." The Niners are expected to re-sign FB Owen Marecic to fill Miller's shoes. RB Anthony Dixon could also be used at fullback.

Cleveland Browns offensive coordinator Norv Turner used RB Chris Ogbonnaya as a fullback in two-back sets during offseason workouts, but said the team is likely to keep a traditional fullback in the offense. When asked if Ogbonnaya, a tailback, can fill that role, Turner said, "He can do some of it." It appears FBs Owen Marecic and Brad Smelley will be fighting for one roster spot.

Cleveland Browns FB Owen Marecic is expected to be on the roster bubble during training camp because the team may prefer to keep a pass-catching running back over a traditional fullback. RB Chris Ogbonnaya and TE Brad Smelley worked in the backfield during offseason workouts.
